Linux Kernel Makfile 之 “make mrproper”

本文介绍Linux Kernel 的命令“make mrproper”，网络上有位同仁写的就很不错，这里只做转载，原文地址如下： http://www.cnblogs.com/laojie4321/archive/2012/04/11/2442921.html

Linux下面去编译项目之前，一般常会用make mrproper去先删除之前编译所生成的文件和配置文件，备份文件等，其中，mrproper和distclean，clean之间的区别，Linux内核源码根目录下面的makefile中，有很清晰的解释：

help:

@echo  'Cleaning targets:'

@echo  '  clean      - Remove most generated files but keep the config and'

@echo  '               enough build support to build external modules'

@echo  '  mrproper   - Remove all generated files + config + various backup files'

@echo  '  distclean  - mrproper + remove editor backup and patch files'

mrproper到底是什么意思呢？为什么起了个这么个看起来如此诡异的名字。在英文wiki对Mr. Clean的解释提到了此点：

http://en.wikipedia.org/wiki/Mr._Clean

“make mrproper” is a command in the Linux kernel build system, used to “clean up” all files from past builds and restore the build directory to its original clean state. The reason “make mrproper” is used instead of “make mrclean” is because Linus Torvalds, the father of Linux, was familiar with the name “Mr. Proper” as this is the brand widely known in Europe.”
